PURIFICATION METHOD AND THE APPARATUS OF DECANTER AND SLOPE FAST PRECIPITATOR FOR GROUNDWATER OF UNDERFLOW

摘要

An apparatus of purifying a decanter and a slope fast precipitator for groundwater of underflow is provided to precipitate suspended material particles of underwater rapidly, to collect supernatant in which the suspended material is removed with non-power and to supply the collected supernatant to a recharge well. An apparatus of purifying a decanter and a slope fast precipitator for groundwater of underflow comprises a high speed sedimentation system(10) precipitating rapidly suspended materials of underwater, a buoy(30) rising to water surface of a cistern in both sides of the fast precipitator and a decanter collecting supernatant cleaned up to a high speed and supplying it to a recharge well. The high speed sedimentation system precipitates and purifies at high speed the suspended materials by setting up inclined plates.
